1. Who We Are
SiteGrade is operated by NuStack Digital Ventures LLC ("NuStack", "we", "us", "our"). This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information.
2. Information We Collect

- Name — optional, collected when you unlock your report
- Website URL — the URL you submit for auditing
Information collected automatically
- Usage data — pages visited, time spent, audit completions (via Google Analytics)

4. Website Crawling
When you submit a URL, our system fetches publicly accessible pages from that website to generate your audit. We do not store the raw HTML of crawled pages. We extract and store only the signals needed to produce your report (e.g., title tag presence, word count, heading structure). Crawl data used for caching is retained for a maximum of 6 hours.

All service providers are bound by data processing agreements consistent with applicable privacy law.
6. Data Retention
